The preferred construction of block' is shown n Figs. 4 and 5, and itis formed.

with hifgroove 4 in the edge'fijand and of.

groove '5 1n the adjacent edge -10,'iind""is also provided witha tongue or rib 6 which.

projects partially from the edge Tand partially from the edge 8, Both the grooves 4, 5 and thei tongue 6 are situated centrally of the block dad are in' thesame plane, and

as a result, the edge 11 of the tongue 6 terminates between theedges 8 and 9.0f the block and in line' with-the :bottom of the groove 4, while the edge 12 of .thetongue 6 terminates between the edges 7 and 10 of the block and in line with the ,bottom of the which extend t groove 5. The tongue 6' is of. such a shape that its edges 13 and Marc a slightly less distance from the edges 7 and8 of the block than the depth of the-grooves t and 5. v

' The inner faces ofthe'sides 15-and 16 of the frame are rovided withribsl? and 18 he length thereof and which areadapted to be received in eitherthe grooves 4 or 5 of the blocks, while the sides 19 and 20 of the fraine are provided; on

their inner faces with grooves 21 and 22v adapted to receive the tongues 6. When the blocks are assembled in the frame the tongue 16of eachblock occupies either a ortion of the grooves 4 and 5 of another b ock, or a ortion of the groove 4 of another block and a portion of the groove 21 of the frame.

Similarly, the'ribs -17 and 18' of the frame v occupy the grooves 4 and 5 ofthe blocks adjacent to the sides 16 and 15 of the frame. It will be understood, of course, that there is always one vacant space 3 in the frame and because of thetongueand-groove con.- struetion above described any block adj acent the vacant space in, the frame can be readily moved into the vacant space, and in doing so the tongue of the block slides through the grooves of adjacent blocks or through the gl'OOVOS 21, 22 of the frame. Moreover, be-

' cause of the tongue-aml-groove construction allthe blocks including those which'engage the frame and also the blocks in the center of the opening in,:thc frame are interlocked with each other and are incapable of bein removed from the fraine, while at the samef" time capable of being freely moved as nee-'5 essary in the solution of-the puzzle. Tn this x construction vbothfaces of the? blocks are exposed so that it is possible to; employ one design on one face of the block and another -(le ign"on the opposite face. 'llna-eforc', two-' different puzzles can he united in vtheonearonstructhm. It will-also he noted that the device comprises a frame having an opening, the opposite sides of which are a'greater distance apart than the; diameter ofthe blocks,-t-hat is, the diametrieal ,diineusiomof said opening in either section is equal, to the. combined diameters of a plurality of blocks, and that the blocks frame having an. openi'ng, of a plurality of blocks occupying said opening and movable movable from the frame, the'distance between opposite sides of said opening; being equal to the combineddiameters of a pluralit-y of the blocks and the blocks having -an interlocking connection with eachother.
